The 2014 Sonata Hybrid continues to demonstrate Hyundai's commitment to
innovation with its advanced Hybrid Blue Drive architecture, which features
a powerful 35 kW electric motor, 47 kW Lithium Polymer battery pack and an
optimized hybrid operating strategy. The Hybrid Blue Drive system is paired
with a 2.4-liter Theta II four-cylinder engine that efficiently runs on an
Atkinson cycle and six-speed hybrid automatic transmission to generate 199
combined net horsepower. This advanced powertrain maintains the improved
fuel efficiencies of the Sonata Hybrid by increasing the overall amount of
available electrical drive power, allowing drivers to go further between
fill ups.

As in previous Sonata Hybrids, the 2014 Sonata Hybrid features a clutch
to couple the gasoline engine with the drivetrain. When in pure electric
drive, the Sonata Hybrid can drive electrically up to 74 miles per
hour.

The 2014 Sonata Hybrid utilizes the all-electric mode during optimal
moments such as highway driving and saves the gasoline engine start-up for
conditions that require a heavier dose of power. All of this translates to
money saved for the driver.

Fluidic Sculpture is the consistent, cohesive design language used
throughout the entire Hyundai showroom. It gives the Sonata Hybrid an
upscale appearance along with aerodynamics that helps reduce wind noise and
improve fuel economy. The unique front fascia and rear bumper with LED
accent headlights and LED taillights boost the flowing lines and integrate
a new level of design precision. The fluid and precise exterior theme is
completed by a set of 17-inch eco-spoke wheels on the Sonata Hybrid
Limited.

LITHIUM-POLYMER BATTERY TECHNOLOGY

The 2014 Sonata Hybrid features a lithium-polymer battery pack, which
has been established as the next generation of lithium-ion technology, is
ideally suited to automotive applications thanks to a particularly robust
and reliable chemistry.

The lithium-polymer cells, developed with Hyundai's partner LG Chem, use
a manganese-spinel chemistry that provides an excellent compromise between
power delivery, energy density and thermal stability. Thermal stability is
critical to ensuring durability, effectively eliminating the need to
replace the battery pack during the normal lifespan of the vehicle. The
electrodes in older lithium-ion chemistries expand and contract
significantly with the heating and cooling that naturally occur during
charging and discharging. This thermal expansion causes cracks in the
electrodes, which ultimately reduces the cell's ability to hold a charge.
Manganese-spinel lithium-polymer cells have much lower expansion rates and
are thus able to go through tens-of-thousands of charge cycles even without
having to use a heavier, liquid-cooling system.

LITHIUM POLYMER BATTERY PACK

The 2014 Sonata Hybrid's 47 kW lithium polymer battery pack is more
energy dense than the nickel-metal hydride batteries used in competitors'
hybrid vehicles. At 91 pounds, the lightweight battery helps improve
overall vehicle weight and fuel economy. The improved battery pack is key
to recovering more kinetic energy from braking and charging from the
engine, when needed, to help propel the vehicle. The optimized hybrid
system allows more all-electric driving with additional usable energy
stored in the battery, cutting both fuel consumption and emissions.

POWERFUL OUTPUT ELECTRIC MOTOR

The 2014 Sonata Hybrid's lithium polymer battery stores more energy,
yielding a powerful output of 35 kW to the electric traction motor. The
higher output electric motor is also essential to improving energy capture
during regenerative braking. The regenerative energy is used for electric
drive mode before the system has to start the internal combustion engine,
sustaining a longer all-electric driving mode for continued fuel efficiency
and improved drivability.

HYBRID STARTER GENERATOR

HSG is primarily used to start the engine and charge the hybrid battery.
The HSG operates at the same 270 volts as the electric traction motor and
battery and is also used to improve clutch engagement when synchronizing
engine to transmission speed. The primary traction motor is coupled to the
transmission and cannot be used to charge the hybrid battery when the car
is stationary. If the battery state of charge is low and the car is
stationary, the HSG will automatically restart the engine, which then
charges the Lithium Polymer battery pack.

When the driver releases the brake and presses the accelerator, the
Sonata Hybrid will pull away smoothly in electric drive mode with the
clutch still disengaged. In this mode, the Sonata will briefly behave like
an electric vehicle. Once the car is in motion and torque demand increases,
the clutch will engage and send engine tractive effort through the
transmission again, which enables the vehicle to achieve exceptionally
smooth starts.

AERODYNAMICS

The body of the 2014 Sonata Hybrid remains unchanged, but it still
features the unique exterior that sets it apart from other Sonatas. The
combination of a re-shaped front and rear fascias with a deeper air dam,
extended rocker panels and lower drag wheels allow air to flow around the
body with less resistance. The drag coefficient for the Sonata Hybrid is an
exceptionally low 0.25 that compares favorably to the Toyota Camry Hybrid
(0.27) and the Ford Fusion Hybrid (0.27).

The ability to easily slip through the air, combined with low rolling
resistance tires and the reduced friction in the optimized Hybrid Blue
Drive powertrain, significantly reduces the amount of energy required to
maintain highway speeds. The result is the remarkable highway fuel
efficiency of the Sonata Hybrid.

HYBRID LIFETIME BATTERY WARRANTY

The 2014 Sonata Hybrid also comes with Hyundai's Hybrid Lifetime Battery
Warranty, which stems from Hyundai's philosophy to make advanced technology
accessible across a wide customer base. The coverage expands the benefits
of Hyundai Assurance, the industry's most comprehensive warranty program,
including an unsurpassed 10-year powertrain warranty.

The Hyundai Lifetime Hybrid Battery Warranty ensures that if the Sonata
Hybrid lithium-polymer battery ever needs replacement, Hyundai will replace
the battery and cover recycling costs for the old battery pack
free-of-charge to the original owner. The coverage is not transferrable,
and does not apply to lease and commercial vehicles or vehicles serviced
outside the U.S.
